A block is given an initial velocity of 7.0 m/s up a frictionless 24 degree incline.
a. what is the block's acceleration as it slides up the plane?
b. how far up the incline does the block slide before coming to rest?
c. after coming to rest the block will begin to slide down the incline. What velocity will the block have as it reaches the bottom of the incline?
